Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden. It discloses the tool's purpose as a connectivity test, which implies it's a read-only diagnostic operation. However, it doesn't specify what 'test' entails (e.g., whether it makes actual API calls, returns specific status codes, or has rate limits).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence with zero waste - every word contributes essential information. Front-loaded with the core purpose ('Test authentication and connection') followed by the specific target ('to the Headlesshost API').

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter diagnostic tool with no annotations and no output schema, the description is adequate but minimal. It explains what the tool does but doesn't describe what constitutes a successful test, what information is returned, or how to interpret results. Given the simplicity of the tool, it's complete enough but leaves some behavioral questions unanswered.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has 0 parameters with 100% schema description coverage. The description appropriately doesn't discuss parameters since none exist. It earns a 4 (not 5) because while it correctly avoids parameter discussion, it doesn't explicitly state 'no parameters required' which could be helpful context.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Test authentication and connection') and target resource ('Headlesshost API'), distinguishing it from all sibling tools which perform CRUD operations on sites, users, or accounts. It precisely communicates the diagnostic nature of this tool.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context ('Test authentication and connection') suggesting it should be used to verify API access before attempting other operations. However, it doesn't explicitly state when NOT to use it or name specific alternatives among the many sibling tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
